Specification of Letters Patent.

Patented July 8,1913.

[o all ie/ioni 2'1 may cci/10cm:

Bc it known that I, REGINA Kanu, a citizen ot' the United States, residing at Milwaukee, county-otl Milwaukee, and State ot' Wisconsin, have invented neu and useful Iniproveiuents in Gaslgniters, oi which the following is a specification.

My iiivcntionvrel-ates to improvements in that class of gas igniters, which are adapted ,to be centrally located between a plurality of gas burners and by which the gas when turned on to any one' or more of said burners, may be instantly ignited by jets of b irnii'ig gas from said central igniter.

-Ileretofore gas has been led to a pilot light located in a central chamber through a separate small capillary tube while a larger volume ot' gas' has been led to and discharged into said central chamber through a larger tube, whereby when desirous to ignite the gas in any one or more ot' said burners, the valve leading to Said central chamber is opened and quickly closed, whereby a radial jet of flame iscaused to Hash out from said central chainber to the several burners of the stove, and wliei'eby the gas in any one or more of said buriierslias been instantly ignited.` By n my present improvement, however, a sepaf rate capillary tube for conducting gas to the pilot light in said central chamber is dispensed with and the required volume ot gas tor maintaining one oi'nioie )ilot lights y in such chamber is led thereto through the main large duct. and the small capillary tube heretofore used yfor maintaining a pilot light in an ignitcr is dispensed with. y

My invention is further explained by reference to the accompanying drawings, in whichM4 Figure 'l represents-a plan View showing a plurality of gas burners and igniter con"- nected with the top ot an ordinary stove. 5 Fig. 2 a side view, part iii section, ot the igniter rei'iiovedtrom' the stove, and Fig. 3 is a section of the coinlnistion chamber of the igniter taken `on lines 3-23 of Fig. 2.

Lilie parts are identified by the same reference numerals throughout the several views.

1 represents the top of a stove of ordinary construction and Q are gas burners used in connection with such stove. The several burners are connected with the main gas supply pipe 3 b the several gas ducts a, and admission ot gas to saidugas ducts and burners is controlled by the several valves 5, all of which parts thus Al'ar described are substantially ol ordinary construction.4

(i represents the central chamber of the igniter. (las is led troni the niain gas supply duct 8 to the chamber through the duct 7.

8 is a spherical valve for controlling the passageof gas from the `main supply duct 3 to the duct 7. The valve 8 is normally retained iii its sciit f) by the recoil'of the spiral spring 10, which spring 10 is interposed between tlie valve 8 and the reducingl coupling l1. The valve 8, spiral spring 1() and reducing coupling 11 are all located within the valve chamber 1Q. The valve 8 is adapted to be opened by pressure upon the push button 13 and the push button 13..

is connected with said valve by the push rod 14, operating through the stuffing nut 15.

It will be understood that. a large volume ot gas is admitted to the central chamber 6 from the main gas duct 3 by opening the valve 8 and that a pilot light or constant llame is ada )ted to be maintained in said cental chamlier (S, whereby when'the valve 8 is opened, the gas which is admitted to said chamber is instantaneously ignited when it flashes outwardly radially, as indicated in lf`igs. 1` and 3, whereby the gas which has been turned on to any one of the several burners 2 is instantaneously ignited as previously stated. The pilot light in the chamber G is constantly maintained in the chamber by admitting gas from the main supply duct 3 through a by pass 16, when it .passes from tliencelo said central chain-4 her G through the valve chamber 12 and gas its duct 7, when `four small radial pilot lig are maintained in said chamber 6. `\Vhen, however, a larger volume of gas is admitted to the chamber (l by opening the valve 8,

such larger volume of gas is instantaneously ignited and caused toilash outwardly radially as heretofore described for the par ose of'lighting the gas in any one or more o the several burners. The passage of gas through the by pass 16 is controlled by the needle valve 1 7 and said valve 17 is adjusted forwardly or backwardly by the threaded member 18 formed integrally therewith, and said member 18 is provided with a knurled head 1,9 by which it Ais turned `forwardly and backwardly when adjusting the needle valve toward or from its seat. 20 represents the Aradial ports through which the gas escapes for maintaining both the pilot.V lights and `producing the radial jets of iame by Which gas is ignited in the several burners. The

ports Q0y are formed in the vertical duct 21, from which the central chamber. 6 is l'supported. The central chamber maybe formed of tWo separate concavo-conveXv disks as shown in -Fig. 2, or it may be formed integrally as desired. l

Having, thus described my invention,vvhat I cla-im as new, and desire to secure by Letters Patent, is

l. The combination with a main gas sup` plyl duct and a plurality of stovetburners, of an igniter comprising a central chamber, a branch duct leading from said main gas lsupply, duct to and extending Within said central chamber,` .said branch duct Within said central chamber provided with a plurality of radial ports, means for supplying a small amount of gas to said'branchV duct continuously from said main duct for supy plying pilot lights at said radial ports, and

an additional means for supplying a larger 'amount of gas to said branch duct intermittently from said main duct for projecting the pilot lights from the central chamber to p the stove burners for igniting the gas in one `or more of said stove burners.

2..Y The combination With a main gas supply duct and a plurality of sto-ve burners,

Vof anv igniter comprising a central chamber,

tently from said main duct for projectingthe pilot lights `from the central chamber to the stove burners for igniting the gas in one or more of said stove burners.

3. The combination with a main gas sup'- ply duct and a plurality of stove burners, ofvanv igniter comprising a central chamber, a branch duct leadingfrom said main gas supply duct `to and extending Within said central kchamber, said branch duct Within said central chamber providedwith a plurality of radial ports, a VVby-,p'ass leading from said main supply duct to the radial ports in said central chamber, a needle valve for closing the passage ofgas through said by-pass, said by-pass being adapted to per; mit a small supply of gas to continually pass to said radial ports, whereby a continuous pilot light is maintained at each of said ra* dial ports, 'and an additional means for sup-- plyin g a larger amount of gas to said branch duct intermittently from said main duct for projecting the pilot lights from `the central chamber lto the stove burners for igniting the gas in one or more of said stove burners.

4. The combination With a main gas vsupply4 duct and a plurality of stove burners, of

an iGniter comprising a central chamber,v a.

branch duct leading from said main gas supply duct to and extending Within said lcdentral chamber, said branch duct Within said central chamber provided with a lurality of radial ports, a by-pass lea ing from said main supply duct to t-he'radial ports in said central chamber, a needle valve for closing the passage of gas through said by-pass, said by-pass being adapted'tc.)v permit a small supply of gas to continually pass.

'to said radial ports, whereby a 4continuous pilot'light is maintained at each of said radial ports, additional means for supplying a larger amountof gas to said branch duct 4intermittently from said main duct for pro- `jecting the. pilot lights from the central chamber to the stove burners for ig'niting the gas in one or more ot' said stove burners, and avalve for manually controlling the admission of such larger supply of gas to said* branch duct.

In testimony whereof I affix my signature in the presence of vtwo Witnesses.
